"There are so many different movements in this game," Gennett said. "Just staying warm and staying loose as much as possible is the key. There's a lot of standing around time on the field. When we get back in or in between innings, I just need to be smart and make sure I'm loose and stretched out."
"He's definitely better," manager Ron Roenicke said before the series opener against the Giants. "I'm being a little cautious with him today. What I've told him is, I don't like that he has to decide which plays he's going to go hard on and which ones he's not. That's never a comfortable thing for me or the team out there, to know sometimes he's going to go hard and sometimes he's not. I'd rather him take an extra day if we need to and then hopefully, he'll get back to where he can go hard every day."
Davis sat with a left elbow issue that he woke up with on Tuesday morning, according to Roenicke. The skipper wasn't sure whether the left fielder would miss more than one day, but he was optimistic that Davis would be able available to pinch-hit on Tuesday.
Rickie Weeks started at second in Gennett's place, while new acquisition Gerardo Parra took over in left field.
"Anytime you can flip somebody in there and you're comfortable with him and know they're a good player, it's always comfortable," Roenicke said.
